Life Expectancy Calculator gives an instant result from your inputs. A life expectancy calculator is popular for insurance and curiosity searches like 'how long will I live calculator'. This page provides an educational estimate range only and is not a prediction. Formula snapshot: We start from a simple baseline expected age and apply small adjustments for common lifestyle factors. Example: Age: 40, Sex: Women, Smoker: No, BMI: 23, Activity: 180 min/week -> Higher remaining-years range vs baseline.
A life expectancy calculator is popular for insurance and curiosity searches like 'how long will I live calculator'. This page provides an educational estimate range only and is not a prediction.
Life expectancy depends on many factors we cannot measure here (genetics, medical history, access to care, environment, and more). We use a simplified, transparent approach based on a few lifestyle inputs.
Use this as awareness: it can highlight controllable factors such as smoking, activity level, and weight status.

Quick definitions for common terms used in this calculator.
Life expectancy
A statistical average, not an individual prediction.
Lifestyle factors
Habits like smoking and activity that can influence health outcomes.
Active non-smoker
Input: Age: 40, Sex: Women, Smoker: No, BMI: 23, Activity: 180 min/week
Output: Higher remaining-years range vs baseline
Smoker with low activity
Input: Age: 50, Sex: Men, Smoker: Yes, BMI: 31, Activity: 30 min/week
Output: Lower remaining-years range vs baseline
